As you indicated " Although we're small, We're an organization playing with ($,Â¥,â?¬,Â£) exchanges" you are on client side rather than on server. If that is right, you do not need to bother with DDoS protection, which is against server side.

Noted the points raised by Jacint and Kelly Keeton. I appreciate that.

May I be kind to seek an opinion/ arguments suggesting if the In-house appliances are more "intelligent" thwarting the application level DOS/ DDoS attacks as compared to ISP provided DOS protection wherein it may even fail to detect them. or if there are other benefits owning an In-house product?

As far as Cons are concerned, I feel that the appliance may add some latency which may create issues wherein a latency of milliseconds count.

Although we're small, We're an organization playing with ($,Â¥,â?¬,Â£) exchanges and heavily regulated by the Government.
